square miles

Explanation:

Step1: Convert percentage to decimal

To find the area covered in water, we first convert 71% to a decimal. 71% is equal to $0.71$.

Step2: Multiply by Earth's surface area

We multiply this decimal by the Earth's surface area of $196900000$ square miles. So the calculation is $196900000\times0.71$.
Calculating this: $196900000\times0.71 = 196900000\times\frac{71}{100}=1969000\times71 = 139799000$.

Answer:

139799000
